Postdoctoral Position available in proteomics/mass spectrometry at 
Cornell University (CU), USA van Wijk lab

A postdoctoral position (2-3 years) is available to work on 
comparative proteomics of chloroplast mutants and protein-protein 
interactions in Arabidopsis thaliana. Focus will be on the functional 
role of plastid-localized Clp protease complexes and thylakoid 
proteins of unknown function. The applicant will use state-of the art 
comparative proteomics tools, including stable isotope labeling (e.g. 
ICAT, ITRAP) and mass spectrometry (MALDI-TOF MS, LC-ESI-MS/MS, 
MALDI-TOF-TOF). Mass spectrometers and other proteomics 
infrastructure are available within the van Wijk lab, as well as the 
Biotechnology Center at CU.

Information concerning plastid proteome analysis is available via the 
Plastid Proteome Data Base PPDB at For

The postdoc will work together in a team of 10-12 molecular 
geneticists, biochemists and plant biologists and is expected to 
interact on a regular basis with bio-informaticians.

Application Instructions: Applicants MUST have a very strong 
background in protein chemistry AND mass spectrometry, as is 
evidenced by one or more strong publications in International 
Journals. Do not apply if you don't have experience with mass 
spectrometry on proteins and peptides.  Send your CV and the names of
